Complete Explanation:An elaborate martial allegory of the United States. Liberty or Columbia, wearing a Phrygian cap and armed with sword, shield, and American flag, is enthroned in the clouds. The words "E Pluribus Unum" and an arc of thirteen stars appear above her.

Below, an eagle perches atop a shield with the stars and strips. In his talons he holds arrows and an olive branch. At left stands an American Indian, with a bow in his hand. At right is a sailor with an anchor and four flags. Around the base of the shield are muskets, tomahawks, cannon, cannonballs, and a sword.
Below, almost hidden in darkness, is a Union encampment (left) in sight of the U.S. Capitol and the Potomac River (right).
